Does this make me a selfish son?

I have asked my parents very nicely to let me prepare my own meals. My doctor said I need to lose 50 pounds, and stick to vegetables/fruits, nuts and fish or else I'm at risk for liver-failure. My parents don't want to work with me. Whenever I say: "no, thank you. I'd rather make my own food... show more I have asked my parents very nicely to let me
prepare my own meals. My doctor said I need
to lose 50 pounds, and stick to vegetables/fruits,
nuts and fish or else I'm at risk for liver-failure.
My parents don't want to work with me.

Whenever I say: "no, thank you. I'd rather make
my own food please."...mom gets hysterical,
starts throwing things, and acts like she's going
to disown me. Dad says I'm being very rude and
I'm not allowed to go to the market.

I feel I have done nothing wrong. Your thoughts?
